System principle, system working principle is simple, using the photovoltaic effect principle of solar cells, solar panels during the day to receive solar radiation and translated into electricity output, after stored in the lithium battery charge and discharge controller, the night when the intensity of illumination is gradually reduced to about 10 lux, solar panels open circuit voltage is 4. Around 5 v, charge and discharge controller to detect the voltage value of the action, the lithium battery to discharge lamp holder. Lithium battery discharge after eight hours, charge and discharge controller action, lithium battery discharge end. Main function is to protect lithium battery charge and discharge controller.
solar power system working principle:
in the daytime, under the condition of light, solar battery components produce certain electromotive force, through component of series-parallel solar cell phalanx formation, makes the square voltage to achieve the requirement of the system input voltage. Again for lithium battery charging, the charging and discharging controller will be used by light conversion of electrical energy storage. Night, lithium-ion battery pack for inverter input power, through the role of the inverter, to convert direct current (dc) to alternating current (ac), to the power distribution cabinet, the distribution function of switching power supply. Discharge of the lithium battery by the controller to control, ensure the normal use of lithium-ion batteries. Photovoltaic power station system should also be limited load protection and lightning protection devices, in order to protect the loading operation of the system equipment and from lightning strikes, protect the safety of the system equipment use.
the advantages of lithium battery of solar street light:
1 using solar photovoltaic cells, solar street light, solar energy as a kind of green environmental protection new energy, & other; Throughout limitless reserve, using them all &; 。 Make full use of solar energy resources, to relieve the tense situation of conventional energy have positive significance.
2, solar street lamp installation is simple, convenient, need not like ordinary street lamp do laying cable, such as a large number of foundation engineering, only need to have a fixed base, all the lines and control parts are placed in the lamp, to form a whole.
3, the operation of the solar street lights maintenance cost is low. Using solar power, solar street lamps in addition to the rainy day into a mains power supply will produce a small number of electricity cost, operation cost is almost zero. The whole system running are automatic control, without human intervention, almost do not produce maintenance costs.
the place on put together is narrated, lithium electricity solar street light has the congenital advantage, since the market is becoming more and more big.
